NUMERICAL SIMULATION OF DETONATION PROCESS IN A TUBE

An orthosis for providing abduction to a patient's legs comprises first and second leg engaging portions configured for operatively engaging first and second legs of the patient and at least one inflatable bladder generally between and operatively attached to the leg engaging portions. The bladder has at least one port for introducing fluid into and removing fluid from the bladder thereby to inflate and deflate the bladder. The bladder is positioned relative to the first and second leg engaging portions so that the bladder resists movement of the leg engaging portions toward each other when the bladder is inflated to maintain the first and second leg engaging portions spaced apart and thereby to maintain the legs of a patient wearing the orthosis spread apart.
